Yes, you can easily drag and drop your books the same as you do on your K3. There's really no disadvantage to not registering it other than some features will not be available to you. You also won't be able to buy books from Amazon to use on it.

Didn't register mine because of privacy issues and because I sideload books from my computer. I use calibre to manage my collection and convert epubs for use on my Kindle. If not registered, you can't use collections, syncing with other devices, cloud storage for Amazon-purchased items. You avoid the special offers if you don't go online.

For me, collections were necessary. Fortunately, there is a jailbreak and a separate collections manager that works well. There are also some patches available that further enhance the Paperwhite's reading experience. By not going online, you avoid any automatic firmware updates that would disable these.

I've just ordered a Paperwhite with offers as that was the only one I could get to come to Australia. I know I can register it and pay $20 to remove the offers, but if I don't register it will the offers even appear?

The offers appear once you open an online connection; the device automatically phones home. Since I haven't had to buy any new books, I put my Paperwhite in airplane mode first thing to save battery power, and a connection was never made. I haven't had any offers appear.

That's what I really wanted to know. Thanks for that. And if you register I presume that every time you turn the wireless on it synchs with Amazon and uploads details of everything on your Kindle? I don't like that thought.

There will be certain free books you can download on your pc and transfer to the PW, while other 'free' books (mainly those that cost a few bucks, but got everything discounted, resulting in a free book; like an amazon special of the day/week or something) won't be able to open on the device (because they're registered to be read on your PC only.
